Can also be supported at the lower end of the first vertical leg located rearward. Therefore, it is possible to prevent the first weight of the first seat and the weight of the seated person from being transmitted to the first slider. Since it is not necessary to support the weight of the first seat and the weight of the seated person with the first slider, the first slider can be kept compact, and the degree of freedom of design can be increased by downsizing the first slider. be able to.
  • the front portion of the first horizontal portion is rotatably supported by the first slider via a rotation shaft extending in the sheet width direction. Therefore, it is possible to prevent the weight of the first seat and the weight of the seated person from being transmitted to the rotation shaft.
  • the weight of the first seat and the weight of the seated person need not be supported by the rotation shaft, the rotation shaft can be suppressed in a compact manner, and the degree of freedom in design can be increased by downsizing the rotation shaft.

  • the restricting member includes the first seat.
  • the operation strap is bent in a direction substantially orthogonal to the predetermined direction. Therefore, the operation member can be prevented from being pulled in a predetermined direction by the restricting member. Since the pulling operation of the operation strap in a predetermined direction can be prevented only by bending the operation strap with the restriction member, the restriction member can be configured with a simple configuration.
  • the seat device includes a first position disposed on a bottom surface side of the first seat cushion in a state where the first seat cushion of the first seat is held in the sitting posture, A support member is provided that is movable between a second position that protrudes below the lower end of the first seat cushion when the one seat cushion is moved to the storage position.
  • the support member is supported by the first seat cushion so as to be rotatable (swingable) between the first position and the second position. Specifically, when the first seat cushion is moved to the sitting posture, the support member is stored in the first position on the bottom surface side of the first seat cushion. Therefore, there is no possibility that the support member will interfere with the person sitting on the first seat cushion.
